First of all, look at the real Zippo lighter. There is a circular gravure on the top and bottom of the joint. It is really difficult for the two circular marks of the pressing blade on the casing to be exactly the same on the copying machine, which can also be used as a basis for judgment. The real Zippo has a year's manufacturing time at the bottom. 1932- 1956 is written in block letters; 1957- 1976 is written in italics; Since 1977, the trademark modeling of flame pattern has been used. In addition, starting from 1957, the base of ZIPPO lighters is engraved with a mark representing the year of manufacture, which is convenient for collectors to identify. Before that, products could only be judged by S number or design type. There are four marks representing the year of manufacture, namely [] (from 1957), [|] (from 1966- 1973) and [/] (from1974-1983). Each sign is used for 8 years. There are at most eight of these marks, which are engraved on the left and right sides of the ZIPPO trademark (that is, each mark has at most four marks). However, with the method of decreasing year by year, at least 1 remains. Since 1986, in addition to the year, the month mark has been added. On the right side of the trademark, Roman numerals indicate the year of manufacture (II stands for 86 years, III stands for 87 years, and IV stands for 88 years); The English letters on the left represent the manufacturing month (A stands for 1 month, B stands for February, and C stands for March). Among the above features, fake Zippo lighters are generally absent or incomplete, and the printing is also very rough. Performance, quality and appearance are not comparable to real Zippo. In addition, we can also compare the actual use of true and false Zippo. First: the real Zippo is generally lighter than the fake, because the fake Zippo lighter is made of steel or iron, not the special material of Zippo; Some unscrupulous manufacturers have increased the thickness in pursuit of hard shell. Second: look at flame and heat resistance. When the Zippo imitation burns, smoke comes out, the flame flickers, and the whole fuselage burns in less than 4 minutes. Real Zippo lighters will only ignite the fuselage after the fuel consumption is exhausted. This is because the cover just made by fake Zippo is too thick and the heat dissipation effect is poor; The oil storage cotton core in the machine is of poor quality and easy to leak oil. Third: windproof ability. Put the true and false Zippo at a distance of 40 cm from the electric fan, and turn the electric fan to the maximum wind power, but it still can't blow out the flame of the true Zippo lighter. The fake Zippo lighter was blown out when the electric fan only turned on the minimum wind. This is because the real Zippo lighter has a high windproof wall; The design of exhaust hole is reasonable; The special wick has good oil absorption performance. /user/icedot _ t/2005-09/45271.html Zippo lighter has become a fashionable toy for a gentleman to some extent, even though he can't smoke at all. However, there are many counterfeit zippo lighters on the market at present, and there are several keys to distinguish the authenticity of Zippo. First look at the appearance. There are circular intaglios on the joints of real Zippo lighters. It is really difficult for the two circular marks of the pressing blade on the casing to be exactly the same on the copying machine, which can also be used as a basis for judgment. Secondly, the real Zippo has a manufacturing year at the bottom. 1932- 1956 is written in block letters; 1957- 1976 is written in italics; Since 1977, the trademark modeling of flame pattern has been used.

Among the above features, fake Zippo lighters are generally absent or incomplete, and the printing is also very rough. Performance, quality and appearance are not comparable to real Zippo. We can also compare the actual use of true and false Zippo. First: weight. Real Zippo is generally lighter than fake, because fake Zippo lighters are made of steel or iron, not special materials for Zippo; Some unscrupulous manufacturers have increased the thickness in pursuit of hard shell. Second: look at flame and heat resistance. When the Zippo imitation was burning, smoke came out and flames swayed, and the whole fuselage caught fire in less than 4 minutes. A real Zippo lighter won't ignite the fuselage until the fuel runs out. This is because the cover just made by fake Zippo is too thick and the heat dissipation effect is poor; The oil storage cotton core in the machine is of poor quality and easy to leak oil. Third: windproof ability. Put the true and false Zippo at a distance of 40 cm from the electric fan, and turn the electric fan to the maximum wind power, but it still can't blow out the flame of the true Zippo lighter. The fake Zippo lighter was blown out when the electric fan only turned on the minimum wind. This is because the real Zippo lighter has a high windproof wall; The exhaust hole design is scientific and reasonable; The special wick has good oil absorption performance.
